What should my facebook adset budget be?

People always ask me this question and me, myself sometimes lose confidence in which budget to set. But today, I noticed something while looking over stats inside Business Manager..

The adset when it receives 50 conversions, it will change from Active (Learning) to Active – Initial Learning Complete.

People always said “FB Needs 50 conversions in a week (if you have that window set) to start optimizing. What optimizing means is to show your ad to people that look like the ones who converted… I was lime mkay, cool it needs that, but only now I realized what that is in reality thanks to these little footnotes FB now provides.

So what should your adset budget be?

Let’s say your offer payout is $35. You want to make 100% ROI on that. That means your CPA you want is $17.5 – since FB needs 50 conversions to optimize, your budget in a week to properly test this would be 50 * 17.5 = 875 / 7 = $125 per day for the adset.
